Improve operator workflow QoL (#5291)

## Thinking Path

> - Paperclip is a control plane operators use repeatedly to supervise
agent companies.
> - Common operator workflows depend on fast scanning of inboxes, issue
sidebars, workspaces, cost totals, and runtime services.
> - Several small UI and service gaps made those workflows slower or
less clear.
> - This pull request groups the operator-facing QoL changes that can
stand alone from recovery and adapter work.
> - The benefit is a denser, clearer board experience for issue triage
and workspace operation.

## What Changed

- Added inbox assignee/project grouping and issue list token/runtime
totals.
- Improved issue properties with removable blocker chips and workspace
task links.
- Improved execution workspace layout, runtime controls, issues tab
default, and stopped-port reuse behavior.
- Added mobile markdown/routine dialog fixes, page title company names,
sidebar polish, and dashboard run task label cleanup.

## Verification

- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run ui/src/lib/inbox.test.ts
ui/src/components/IssueProperties.test.tsx
ui/src/components/WorkspaceRuntimeControls.test.tsx
server/src/__tests__/workspace-runtime.test.ts
server/src/__tests__/costs-service.test.ts`

## Risks

- Medium UI risk because this touches several operator surfaces. The
branch is intentionally grouped around workflow/QoL files and keeps the
file count below the Greptile limit.

## Model Used

- OpenAI GPT-5 Codex via Paperclip `codex_local` adapter, with
shell/git/GitHub CLI tool use.
